摘要
目的:建立南、北五味子中微量元素的测定方法,比较其含量异同。方法:采用湿法消化法处理样品,用火焰原子吸收光谱法测定南、北五味子中微量元素的含量。结果:南、北五味子中均含有Fe、Cu、Zn、Mn微量元素。结论:同种微量元素含量南、北五味子不甚相同。该测定方法简便,精密度及重复性均较好,结果令人满意。
Objective：To establish the method for determination of the content of microelements in the Schisandra chinensis and Schisandra sphenanthera, compare the similarities and differences in the contents of them. Methods： Wet digestion method and atomic absorption spectrometry method was established for the determination of microelements in the Schisandra chinensis and Schisandra sphenanthera. Results： The microelements Fe、Cu、Zn、Mn was contained in the Schisandra chinensis and Schisandra sphenanthera. Con-clusion： The contents of homogeneous microelements in the Schisandra chinensis and Schisandra sphenanthera are not the same. The method is quick, simple and convenient, the results are satisfactory.
